Product Introduction

illustrate

The LM26484 is a versatile, configurable power management unit. The device integrates two high-efficiency 2.0A step-down DC/DC converters, an LDO controller, power-on reset (power-on reset) circuitry, and overtemperature protection circuitry. All regulator output voltages are externally adjustable. The LDO controller is a voltage regulator for low voltage NMOS. The LM26484 supplied is in a 5× 4 × 0.8 mm law firm in a 24-pin package.
